Isidor's Eagle - Framed Picture - 20" x 16"


The black-and-chestnut eagle (Spizaetus isidori) is a South American species of bird of prey in the Accipitridae family. It is sometimes called Isidor's eagle.

This is a fairly large eagle at 25–29 in long with a wingspan of 58–66 in. As an adult, this species is glossy black on the head and the back and a streaky chestnut on the underside, much of the wing primaries and legs.

They are known to prey on woolly monkeys, porcupines, coatis and other mid-sized arboreal mammals. Large birds such as guans are also taken. They frequently have much abraded tails by plunging after prey through the branches. They overlap in range with several other large forest eagles, including solitary eagle and possibly other Spizaetus eagles, but no interactions have been reported and the black-and-chestnut eagle is believed to be normally the top avian predator in its range.

It is found humid montane forests, normally at elevations between 1,800-2,500 meters, in the Andes from northern Argentina, through Bolivia, Peru, Ecuador, Colombia, to Venezuela, with isolated populations in the Venezuelan Coastal Range, Serranía del Perijá and Sierra Nevada de Santa Marta.
